[0015] In the drawing: the liquid collecting barrel 1, the footboard 2, the drain pipe 3, the core sampler 4, the lower sealing device 5, the upper sealing device 6, the annular outer ring 7, the notch 8, the closed brush 9. Specific embodiments

[0016] The utility model will be described in further detail below in combination with the drawings and specific embodiments:

[0017] As Figure 1 shown, a kind of road drilling sampling auxiliary device, including liquid collecting barrel 1, the upper portion of liquid collecting barrel 1 is provided with core sampler 4, the outer side of core sampler 4 is sleeved with sealing device, sealing device rotates with the rotation of core sampler 4 and rotates to realize the plugging of annular gap formed by liquid collecting barrel 1 and core sampler 4, to avoid mud liquid in core sampler 4 splashes outward.

[0018] As Figure 3 shown, sealing device includes upper and lower two interval settings upper sealing device 6 and lower sealing device 5, lower sealing device 5 is generally at the position of concrete coring depth (concrete coring depth is generally 10cm), the position of upper sealing device 6 can be adjusted in situ height with the position of liquid collecting barrel 1, when lower sealing device 5 is submerged in drain pipe 3, upper sealing device 6 is in the inside of liquid collecting barrel 1, when lower sealing device 5 is submerged in drain pipe 3, there will be mud in its upper portion, and at this time, upper sealing device 6 is in the inside of liquid collecting barrel 1 and forms top sealing layer, to avoid mud splashes outward.

[0019] As Figure 2 shown, upper sealing device 6 and lower sealing device 5 include annular outer ring 7 that is sleeved on the outer side of core sampler 4, and the outer side of annular outer ring 7 is provided with a circle of closed brush 9.

[0020] As Figure 3 shown, the length of closed brush 9 is greater than the annular gap interval 3-5mm formed by liquid collecting barrel 1 and core sampler 4, so that even if liquid collecting barrel 1 and core sampler 4 are eccentric with small deviation, the closed layer of longer closed brush 9 can also be formed without dead angle.

[0021] As Figure 2 shown, annular outer ring 7 is made of flexible rubber, which has good elasticity and can be fixed on the outer side of core sampler 4, and a plurality of notches 8 are uniformly opened in the inner side of annular outer ring 7, the plurality of notches 8 can reduce the contact area of annular outer ring 7 and core sampler 4, and annular outer ring 7 is more convenient and easy to disassemble.

[0022] As Figure 1 shown, the footboard 2 is arranged on both sides of the collecting bucket 1.

[0023] The implementation principle of the road drilling sampling auxiliary device is as follows:

[0024] Before the coring machine drives the coring sampler 4 to rotate and sample, the collecting bucket 1 is placed on the road to be sampled, then the coring machine is operated to press down the coring sampler 4, the coring sampler 4 enters along the collecting bucket 1 and contacts the ground, and in this process, the position of the collecting bucket 1 is adjusted to make it concentric with the coring sampler 4 as much as possible (to make the closing bristles 9 of the lower sealing device 5 and the upper sealing device 6 uniformly arranged in the annular gap formed by the collecting bucket 1 and the coring sampler 4);

[0025] After adjustment, the operator steps on the footboard 2 with both feet to fix the collecting bucket 1, then starts the coring machine to press down the coring sampler 4, the coring sampler 4 rotates to drill core and sample the concrete road, the cooling water and mud generated by the coring sampler 4 are in the collecting bucket 1 to avoid leakage and splashing outside, when the cooling water level is higher than the drain pipe 3, the cooling water mixture will flow out along the drain pipe, at the same time, the lower sealing device 5 rotating with the coring sampler 4 will form a dynamic sealing layer between the collecting bucket 1 and the coring sampler 4 to realize the closed area and avoid mud splashing outside along the top of the collecting bucket 1, when the lower sealing device 5 is below the position of the drain pipe 3, the upper sealing device 6 enters the collecting bucket 1 to form a second sealing layer (as shown in Figure 3 ), so as to maximize the prevention of mud splashing outside, and the lower sealing device 5 will continue to move down, at this time, the upper sealing device 6 moves 2-3 cm into the collecting bucket 1, the coring sampler 4 is stopped and taken out to complete the sampling.
